Patent EP-0233273-B1 (EP)
IPC: G01S13/86
Filed: 1986-08-12
Granted: 1992-01-15
Abstract: In a single-frequency precision guidance landing system, the use of a DME interrogator (50) in the aircraft and a DME receiver (60) at the ground installation, each tuned to the same DME channel frequency, to uniquely interrogate a selected ground station (29, 32, 21, 22, 33, 34) and hence identify it by virtue of its replies being synchronous in the aircraft (3, 8) with the interrogations, the interrogations and the replies also being used to obtain range to the ground installation. This technique uses airborne already-installed DME interrogators (50) for selective interrogation of a desired landing installation (60, 29, 32), thereby to eliminate any need to add additional special purpose equipment to the aircraft to accomplish the desired uniqueness of interrogation and ground installation identification achieved by this invention.

Abstract: In a method and apparatus for suitably positioning light waveguides for coupling ends of function fibers at coupling locations, the coupling ends of the function fibers are aligned and fixed on a carrier element. Guide capillaries are formed to fit the jackets of the function fibers precisely and are aligned on both sides of a coupling location. The alignment is achieved with the assistance of a wrap-free auxiliary fiber after which the auxiliary fiber is removed and the function fibers are subsequently introduced into the guide capillaries and fixed therein.

Title: Non-cylindrical reactor for carbon black production
IPC: C09C1/50
Filed: 1988-10-06
Granted: 1992-07-29
Abstract: A non-cylindrical carbon black reactor for consistently and efficiently producing high tint carbon black. A plurality of flat sides defines the inner surface of the carbon black reactor. The flat sides provide a planar surface for the introduction of feedstock hydrocarbon into the reactor, thereby eliminating or substantially reducing impingement of the feedstock hydrocarbon on the inner surface of the reactor chamber and the consequent erosion of the inner surface. The flat sides of the inner surface of the reaction chamber also provide a hot gas flow with a cross-sectional area that substantially conforms to the spray pattern of the feedstock hydrocarbon, thereby providing a minimum flame length within the reactor and a more efficient use of the hot gas.

Abstract: A selective call paging receiver for receiving analog voice information converts the analog information to digital information and stores the digital information in a memory of the paging receiver. In a first embodiment, the paging receiver includes a hardware controlled decoder and an audio producing module. The memory is divided into a plurality of fixed storage areas to allow the decoder to store a digitized voice message in a fixed storage area. If the storage capacity of the fixed storage area is not filled, the audio producing module fills the remainder in a predetermined bit pattern. In a second embodiment, the paging receiver includes a microprocessor controlled decoder. The microprocessor stores a digitized voice message in the memory, depending upon the length of the voice message, thus eliminating the fixed storage area.
